How to set up Html table

HTML tables are one of the commonly used elements in web development. Through tables, data can be presented to users in a clear and organized form, making it easier for users to obtain information.

In this article, we will introduce how to create a table in HTML and how to set the properties of the table, including table borders, cell alignment, table headers, etc. Let’s start learning!

1. Create a table

In HTML, use the f5d188ed2c074f8b944552db028f98a1 tag to create a table. The following is a simple example showing how to create a table with only 3 rows and 2 columns:

<table>
  <tr>
    <td>行1列1</td>
    <td>行1列2</td>
  </tr>
  <tr>
    <td>行2列1</td>
    <td>行2列2</td>
  </tr>
  <tr>
    <td>行3列1</td>
    <td>行3列2</td>
  </tr>
</table>

In the above code block, the f5d188ed2c074f8b944552db028f98a1 label means creating a table, and the a34de1251f0d9fe1e645927f19a896e8 label means creating The row of the table, the b6c5a531a458a2e790c1fd6421739d1c label indicates the creation of the cell. In a table, each cell must be placed within a a34de1251f0d9fe1e645927f19a896e8 tag and identified with a b6c5a531a458a2e790c1fd6421739d1c tag.

2. Set the border of the table

If you want to add a border around the table, you need to use CSS styles to set the border properties of the table. The following is an example of setting a blue border line:

<table>
  <tr>
    <td>行1列1</td>
    <td>行1列2</td>
  </tr>
  <tr>
    <td>行2列1</td>
    <td>行2列2</td>
  </tr>
  <tr>
    <td>行3列1</td>
    <td>行3列2</td>
  </tr>
</table>

In the above example, the c9ccee2e6ea535a969eb3f532ad9fe89 tag is used to define the CSS style. The table's border attribute is set to 1 pixel wide and blue, while the cell's border attribute is also blue and 1 pixel wide. This will allow you to add borders to the table.

3. Set the alignment of cells

If you want the content in the cell to be aligned, you can use the text-align attribute of CSS style. Here is an example showing how to center align cell content:

<table>
  <tr>
    <td>行1列1</td>
    <td>行1列2</td>
  </tr>
  <tr>
    <td>行2列1</td>
    <td>行2列2</td>
  </tr>
  <tr>
    <td>行3列1</td>
    <td>行3列2</td>
  </tr>
</table>

In the above example, the text-align property of the CSS style is applied to all cells. This means that all cell contents in the table will be centered.

4. Set the header

In the table, you can use the b4d429308760b6c2d20d6300079ed38e tag to wrap the content of the first row of cells and mark it as the header. At this time, the cell will be bolded to indicate that it is a header. Here is an example showing how to add a header:

<style>
  th {
    background-color: gray;
    color: white;
    font-weight: bold;
  }
</style>

<table>
  <tr>
    <th>姓名</th>
    <th>年龄</th>
  </tr>
  <tr>
    <td>张三</td>
    <td>25</td>
  </tr>
  <tr>
    <td>李四</td>
    <td>30</td>
  </tr>
</table>

In the above example, the b4d429308760b6c2d20d6300079ed38e tag is used for the header cell. CSS styles are used to change the color, background, font size and other properties of the table header to make it visually distinguishable from the cell content.

Summary

Through the above introduction, I believe readers have understood the basic usage of HTML tables and how to change tables through CSS styles. Finally, I would like to remind everyone that in actual development, tables often use JavaScript or other technologies to interact with the server, making the table a more useful tool.
